The '''mucous membranes''' (or '''mucosae''' or '''mucosas'''; singular '''mucosa''') are linings of mostly [[germ layer|endodermal]] origin, covered in [[epithelium]], which are involved in [[digestion|absorption]] and [[secretion]]. They line cavities that are exposed to the external environment and internal [[organ (anatomy)|organs]]. They are at several places contiguous with [[skin]]: at the [[nostril]]s, the [[lip]]s of the [[mouth]], the [[eyelids]], the [[ear]]s, the [[Sex organ|genital area]], and the [[anus]]. The sticky, thick fluid secreted by some mucous membranes and [[glands]] is termed [[mucus]].<br />
<br />
The [[glans clitoridis]] and the [[clitoral hood]], as well as the [[glans penis]] (the head of the [[penis]]) and the inner layer of the [[foreskin]], are all mucous membranes. The [[urethra]] is also a mucous membrane. The secreted mucus traps the pathogens in the body, preventing any further activities of diseases.<br />
